Drivers and businesses just need to hang on a little longer: The Bluff Street corridor construction project in St. George is 90 percent done, according to the Utah Department of Transportation.

Starting Sunday, crews will start paving the final layer from Sunset Boulevard to Valley View, according to UDOT's website. There will be sporadic closures along the corridor and side streets between 7 a.m. and 9 p.m. Striping and signal work will also be going on during that time. St. George police officers will direct traffic.

Drivers can expect paving to continue overnight, from 9 p.m. until 6 a.m., until the work is done, UDOT says. That is expected to be through Wednesday, but weather or other complications could affect that.

Slow down, officials warn

Once the paving is finished, pavement markings will be made. Officials urge extra caution as the final work continues — there might be lane shifts and new markings, and signals may not be perfectly aligned with the travel lanes.

The speed limit in the construction zone is 30 mph.

The St. George Police Department post on its Facebook page earlier this month a reminder with photos of cars that had been in a traffic accident.

End of the work is near

Some work on the project will last into November. UDOT says that will include landscaping; installation of sidewalks, curbs and gutters; and work on signal lights and trails.

People might have noticed that the asphalt and old materials at Bluff Street and Sunset Boulevard have been removed. Crews are building the grade that will complete the northwest part of the intersection, UDOT says. The upgrades are being done to make the intersection safer and to increase traffic flow.

The pedestrian tunnel remains closed and under construction.

People who want to see how things are progressing without driving along the road themselves can use UDOT's traffic cameras. They are accessible at udottraffic.utah.gov, on the right side.
